Power failure Power failure during operation will stop the unit completely. To restart the operation, we should mention Auto restart function. Heating characteristics Defrosting operation If the outdoor unit is frosted during the heating or hot water supply operation, defrosting starts automatically (for approximately 2 to 10 minutes) to maintain the heating capacity. During the defrosting operation, the defrosted water will be drained from the bottom plate of the outdoor unit. Heating capacity In the heating operation, the heat is absorbed from the outside and brought into the room. This way of heating is called heat pump system. When the outside temperature is too low, it is recommended to use another heating apparatus in combination with the air to water heat pump. Attention to snowfall and freeze on the outdoor unit In snowy areas, the air intake and air discharge of the outdoor unit are often covered with snow or frozen up. If snow or freeze on the outdoor unit is left as it is, it may cause machine failure or poor warming. In cold areas, pay attention to the drain hose so that it perfectly drains water without water remaining inside for freeze prevention. If water freezes in the drain hose or inside the outdoor unit, it may cause machine failure or poor warming. Air to water heat pump operating conditions For proper performance, operate the air to water heat pump under the following temperature conditions: Cooling operation Hot water Heating operation Outdoor temperature : 10 C to 43 C Room temperature : 18 C to 32 C (Dry bulb temp.) Outdoor temperature : 20 C to 43 C Room temperature : 5 C to 32 C Outdoor temperature : 20 C to 25 C Room temperature : 5 C to 32 C If air to water heat pump is used outside of the above conditions, safety protection may work. 12 12-EN
